I hav a PS3 slim 120gb bought from US. Was having the same problem, Bestbuy salesmen said it works on dual voltage, but the guarantee wont cover is something goes wrong. So bought a transformer, it melted after one days use. couldn't be bothered, pluged in it expecting an explosion, it just started right up. Works fine up 2 now. (1 year) only prob wit the US version is u need to hav a TV wit HDMI. and it doesnt hav audio out put. Cant connect it to the home theater system :@
